Specification of Letters Patent.

To all whom it may concern:

Be it known that I, PAUL BROWN KLUGH, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented new and useful Improvements in Adjusting Devices for Musical Instruments, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to mechanism for carrying and propelling the perforated sheet for controlling automatic musical instruments. Its purpose is'primarily to provide for adjusting the sheet to the tracker-board to cause perfect registration of the apertures of the one with the other, and also to shift the registration from aperture to aperture for transposing the music. The means adopted for accomplishing this primary purpose also accomplish a secondary )urpose in connection with the shifting of t e driving power from the rewinding to the take-up roll,

as more particularly pointed out in the following description.

The invention consists of the features set out in the claims.

I11 the drawings, Figure 1 is a plan View of a portion of the roll-operating 0r sheet-propelling mechanism of an automatic player embodying my invention. Fig. 2 is a section at the line 2 2 on Fig. 1. Fig. 3 is a detail section at the line 3 3 on Fig. 1. Fig. 4 is a detail section at the/line 4-4 on- Fig. 1,

The perforated controlling sheet 1 is carried and propelled by the customary take-up roll 2 and rewind-roll 3, Intermediate which is the fixed tracker-board 4, over which the sheet is drawn-in one direction or the other by the operation of the rolls, respectively. A pneumatic motor, whose successively-operating bellows 5 5 5 and triple-crank shaft 6 sufficiently identify it as a familiar type of motor, furnishes the power for driving the rolls through the medium of the train 7 of which certain parts only need be particularly men tioned, as they are concerned in the particular invention to be herein claimed. The shaft 8 of this train, it will be understood, is continuously driven by chain over the wheel 8*, pinned. fast to theshaft, (see Fig. 3,) and the pinion 9 at the inner end of this shaft meshing with the gear 19 on the shaft 11 of the take-up roll 2 drives said roll for propelling the controlling-sheet 1 in the direction for playing. The rewind-roll 3 is driven by means of a sprocket-wheel 12, which is loose on the shaft 8, and from which the chain 13 extends around the sprocket-wheel 14 on the spindle 15, which has the chuck or driving-head 16 for engaging said rewind-roll. The lever 17, operated by the link 18, connected to the stop-lever 19, whose stopfinger 2O protrudes through the slot 21 in the sto board bymeans of the finger 19 engaging t 1e grooved hub of the gear 84, shifts the shaft 8 to the left for carrying the inion 9 out of mesh with the gear 10, and t e same move ment of the shaft carries the clutch member 22, rigid with the shaft 8, into engagement with the clutch member 23, rigid with the gear 12, and so transmits the driving-power to the rewindroll at the same time that it 1s disconnected from the take-up roll by-the disengagement of the pinion 9 from the gear-10.

The shaft 11 on the take-up roll 2 is free to move endwise in its bearings in two cheeks A and B, and at the right-hand end it protrudes past the cheek B, and being tapered to a point bears against the face of a spring C. The shaft or spindle 15 for driving the rewind-roll is movable endwise in its bearings. A spring D, mounted on the left-hand cheek A, operates against the left-hand bearing E of the rewind-roll to thrust said bearing, and thereby the roll and the spindle 15 at the opposite end, to the right. The shaft or spindle 15 and the shaft 11 of the take-up roll are provided with collars F and G, and inbearmgs suitably mounted on the cheek B there is a rock-shaft II, having short lever arms or fingers II and H which extend,respectively,

at the right of the collar F and at the left of the collar G, so that when the position of the rock-shaft II is fixed said lever arms or fingers H and H limit the thrust of the shaft 11 spindle 15, respectively, derived from I the springs C and D and determine the position longitudinally of the take-up and rewind rolls, respectively.

It will be seen that if the shaft is rocked in one direction the rewind-roll will be forced against the spring D, to the left, up roll will be permitted to yleld to the action of'its spring C for movement in the same direction an equal amount, and when the shaft is rocked in the reverse directions reverse movements of the rolls will follow, the takeup roll being in that case forced against the ICC and the take,-

action ofits spring and the rewind-roll permitted to yield to the action ol' its spring. By the rocking of the shalt ll, therefore, the two rolls will be moved simultaneously and equally longitudinally with respect to the tracker-lmard, and thereby the apertures in the sheet may be adjusted thus in respect to the tracker-board, or the adiustment shilted to change the registration for transposition within the limit of the movement which can be thus caused. by the rockshaft, and it will be seen that the limit of range of such movement can be made anything, more or less, as desired, by the adjustment of the rock-shalt H with respect to the two shafts to he moved by it, so as to permit the use of longer or shorter lever-arms H H The width of the pinion 9 wil be made such as to permit such range of movement as the other devices are adapted to cause without carrying the gear 10 out of mesh with said pinion when the stop is set for laying.

it will be noticed that moved to the left for disengagement from the gear ll) when the stop 20 is set for rewinding, and it follows that in moving the stop in the opposite direction to bring the pinion hack into engagement with the gear, if the teeth do not happen to stand at position for immethe pinion ll is diate meshing in the sidcward movement ol' thepinion, the collision ol" the pinion against the side of the gear will move the gear and the roll in the direction which is resisted by the spring 0 and in which, therefore, the ear can yield as the spring C permits. Since the pinion is constantly rotating, it will come into mesh almost instantly, and the purpose of permitting the gear thus to yield in case ot lateral collision of the pinion therewith is thatthereby the operating connections are not strained during the instant ot collision, as is liable to happen when no provision is made for such yielding ol the gear, because the operator is liable to move the stop so quickly and lorcibly that bending of the connections or distortion or dislocation ol the gear or pinion may be caused bclorc the continuing rotation ol the pinion brings it into mesh. For operating thc'roclc-shal't ll it has a lever-arm ll, which extends down through the stop-hoard and below the latter is con-.

nected by a link J with a slop-rod K, which extends up through the stop-board and through a slotted plate held mounted on the top of the board, above. which said stop-rod has a thumb-nut M, operating on the reduced and threaded terminal rod hi to clamp the rod to the. stop-plate at any point to which it may be adjusted. In case the pcrl'orated controlling-sheet is irregular or warped so that the lines of perforationsdo not run true the operator holding the stop-rod h means of a thumb-nut and having the latter slacked. so as not to clamp it to the plate, can shill the rolls back and l'orth the small l l l l l l l l l l l l l l l l l l y l l l l l put in place and clamp the nut .\l to hold therolls in the posil l l l l l tion to which the may he thus athusted.

To diminish the friction that might be caused between 1 he lingers ll and ll" and the collars l and (.r, respectively, these lingers may he provided with an anlil'riclion-roll It 7L2, respectively, whose axes are substantially radial lo the shafts l and 11, respectively, the rolls being convex outwardly in radial section, so as to present their surfaces properly to the llangcs at ihe dill'erent angles at which the pressure may be exerted in the dillerenl adjustments ol' l he rock-shalt H.
